Difference Between Wireless G and Wireless N Routers (With Table)

Routers are devices that form networks of computers or connect computers with the global internet. It is a device used to connect devices and connect them to the internet for easy access to the information and data from the internet to be shared across computers or other devices such as smartphones, tablets, laptops, and so on.

Wireless G vs Wireless N Routers

The difference between wireless g and wireless n routers is that they differ mainly in their data transfer speeds. This is the reason due to which they are set at different standards of G and N routers in the wireless category as prescribed by the Institute of Electrical and Electronics Engineers.

Wireless G Or Wireless 802.11 G routers are devices that connect computers Or any other electronic devices to the internet or connect the devices. These routers have an average speed of data transfer of 54 megabytes per second and have a sufficiently large range of network coverage.

Wireless N or Wireless 802.11 N routers are similar devices that connect the computers or any other electronic devices to the internet or connect the devices. These routers have an average speed of data transfer of 300 megabytes per second and a large range of network coverage.

What are Wireless G Routers?

Wireless G or 802.11 G routers are a type of routers as specified by the standards of IEEE or Institute of Electrical and Electronics Engineers. Wireless G routers were launched before wireless n routers and have been in the market for a long time. These routers help devices connect to the internet as well as to each other.

Wireless G routers are the basic type of routers for simple actions. They have an average data transfer rate of 54 Mb per second, which means data can be downloaded or shared through the internet at the speed of 54 Mb per second, which means about 54 Mb of data is downloaded in one second.

These routers can connect to with network of frequency of 2.4 GHz. However, due to 2.4 GHz being a common frequency of networks, wireless g routers do face interference problems with devices using the same frequency bandwidth. Usually, these routers are provided with one antenna.

These routers, however, can function in small workspaces only as they have less range of network. It can work in small office spaces or homes. The channel width, however, for these routers is 20 MHz. Thus these routers are sufficient in function for work from home or small offices.

What are Wireless N Routers?

Wireless N or 802.11 N routers are a type of routers as specified by the standards of IEEE or Institute of Electrical and Electronics Engineers. Wireless N routers were launched after wireless g routers and hence are an update from the previous one. These also have the same basic functionality as the wireless g routers.

Wireless N routers are routers that can be used for heavier work purposes with multiple devices connectivity. They have an average data transfer rate of 300 Mb per second. The high speed of these routers is attributed to the Multiple Input and Multiple Output technology or MIMO technology that has a large number of transistors and receivers that handle data packages.

Also, wireless n routers have dual-band functioning. This means they can work with both the frequency rate of 2.4 Hz as well as 5 Hz. This enables them to avoid the problem of interference. This they can switch from using any of the two bands of frequency as per the needs of the device, and It’s the user.

With a channel bandwidth of 40 MHz, this router also has a large range of networks. This is possible because wireless n routers employ beamforming technology, due to which its network can travel long ranges without being hindered. These are ideal for large workspaces.

Main Differences Between Wireless G and Wireless N Routers

  1. Wireless G routers face interference problems, while wireless n routers do not face any such difficulty.
  2. Wireless G routers do not employ the MIMO or multiple input and multiple output technology, but wireless n routers do.
  3. Wireless G routers do not also have beamforming technology while wireless n routers have.
  4. Wireless G routers usually have only one or two antennas, while wireless n routers have more antennas.
  5. Wireless G routers have a lower speed of data transfer, while wireless n routers have a higher speed of data transfer.
  6. Wireless G routers have a broader range of networks in comparison to wireless n routers.

Conclusion

The standards of wireless routers are set by their speed and range. Wireless n routers being a later addition to the router family, have improved qualities over the wireless g routers. The choice of the usage of routers, however, depends on the user.

In case of small areas with few devices to be connected, like in the case of work from home or connection within small offices or cafes a wireless g routers suffice the function, but for larger areas with the need of high-speed internet wireless n, routers are needed because it has better specifications than the other router.
